IMO, best episode of the season so far. Best written. directed, and acted.
Loved Heather and Valencia's interaction. The "conversation" they had where Valencia just reacted with her face to Heather's questions, suggestions, and assumptions, was brilliant. Loved "Bart" sliding drinks and food which all came to an abrupt stop in just the right places. But the icing on the cake of course, was finding out that Valencia's high school boo was Father Brah. Perfect. Totally unexpected.
I wondered during the episode if recasting Greg was done on purpose or if they couldn't get Santino back. Ultimately, I didn't think it mattered because I thought bringing to life the whole '(your ex) looks like a completely different person" cliche in the literal way they did, was great. However, the new dude can't sing like Santino.
Glad Rebecca told him what she'd done.
Josh, White Josh, and Hector together were hilarious. Josh is a more rounded person, but he can still be clueless.
I only got the episode's writer's first name (think it was Rene), but I hope he or she does more after the hiatus.
